Hi there,

Thanks for contacting us. Sorry for the inconvenience. I have added this css code inside the custom.css file.

.sp-megamenu-parent .sp-dropdown li.sp-menu-item>a:before, .sp-megamenu-parent .sp-dropdown li.sp-menu-item>span:not(.sp-menu-badge):before {
    content: "";
    position: absolute;
    left: -30px;
    width: 0;
    height: 1px;
    background-color: #17161A;
    top: 50%;
    transform: translateY(-50%);
    opacity: 0;
    transition: 0.3s;
}

.sp-megamenu-parent .sp-dropdown .sp-dropdown-inner {
    box-shadow: 0px 9px 16px rgb(45 46 48 / 8%);
    border-radius: 10px;
    padding: 30px;
    overflow: initial;
}

-Thanks
